Help, my husband is a minute man....?

I have been married to him for 6 years, been together 7. He is good in bed but just doesn't last very long at all. He blames it on me having a tight ...but seriously after all of this time I am getting sick of it. I just feel like he's not 16 anymore, he's 31 and he should be able to control himself better. Put it this way, I love to give him and I know that I please him...but what if I gave up on it after a couple minutes and just didn't care about getting him off? I'm fed up with it and would honestly consider going elsewhere for it if it doesn't change. Suggestions? And I don't even want to hear that I'm fuc*ed up for saying I would go elsewhere because you know if I were a guy who was getting lousy from a woman all you men would sympathize :)
